JPS5839154A - Control system for discrimination of interruption call - Google Patents

Abstract

PURPOSE:To discriminate a calling subscriber without response, by displaying identification information of the calling extension subscriber of a waiting call to a busy extension subscriber. CONSTITUTION:When a call comes from an interruptable extension subscriber C to an extension subscriber A who is speaking to an extension subscriber B, a central controller 2 extracts the extension number of the subscriber C from a main storage device 3 and displays it in the place perceivable by the subscriber A on a display 10 by a display driving device 9 and transmits an interruption tone to the subscriber A. Thus, the subscriber A discriminates the number of the calling subscriber without responding to the calling subscriber when the report of call waiting is received by the subscriber A, and the subscriber A discriminate to which call the subscriber A should give a preference, the collected call or the waiting call.

Description

[Detailed description of the invention] This address @ is an interrupt call identification control method,! Kj1 Concerning an interrupt call identification control method in an automatic private branch exchange equipped with a notification function of a busy incoming call ◎ In recent years, as one of the functions of automatic private branch exchange When a call is received from an extension subscriber that can be called, the call is notified of the arrival of the incoming call (by making the extension subscriber hear an instantaneous interrupt tone), and the call is sent to the extension subscriber who is talking on the m2, etc. The mid-call layer (&Call O
Notification functions are known.

Figure 1 is a diagram showing an example of a conventional interrupt call control method in this private exchange.
2) Assuming that the connection is connected and a call is in progress, when an extension subscriber C who has the qualification to interrupt an officer I/C makes a call to an extension subscriber AK in the middle of the call, the central control Koji device 2 Main memory device 3 Power O Inner Trouble Checking AO status body Looking at the mail to know that the call is busy, refer to the LIC in the subscriber CG data memory and assign it. Knowing that the subscriber has a subscriber capacity that can be accessed, 1 uses a well-known method to connect 1 extension subscriber to the OM path 1-1 to 1-2-1 in the network 1 for a short time.

is connected to Shinroku, and waits for extension subscriber 2A's response while listening to the interruption notification tone. ・Extension subscriber A, who heard the interruption tone during the call, learns that the call has arrived at Shinroku and hooks up. If you do it 1
The central control unit 2 detects the call and sets communication paths 1-4 and 1-5 in the network 1 using a known interrupting call control method, and the internal line subscriber A is connected to the internal dispute subscriber C. <Let the implosion subscriber BVc#i hold tone to listen to the hold tone sent from the trunk 8. 0 When the subscriber A responds, it is not until the subscriber A has answered that the incoming call is being called by the subscriber C. The call with extension subscriber B, who is on hold, has arrived.
If w, 1 hooks again, causing the central control unit '12 to reset the call path 1-1 within the network], returns to the call with extension subscriber B, and connects extension subscriber CK.
Id Setting a route not shown in the figure to listen to the hold tf sent from the hold music trunk 8 and make the user wait.
From the explanation of 0 or more taking IIIt, in the conventional lead-in call control method 2, subscriber A can detect the arrival of a damaged call during a call by listening to an interrupt sound. mh
Therefore, it is not notified that extension subscriber C is the calling party of the scissors incoming call. Therefore, once an incoming call is answered and the calling party is confirmed, it is necessary to decide which notification of extension subscriber B or C should be given priority. An interrupting call notification that eliminates the shortcomings of certain interrupting call control methods and allows an extension subscriber who receives notification of an incoming call to identify the caller of the incoming call in advance without responding. The purpose of this is to provide a display device that can be sensed by the extension subscriber who is talking in an automatic private branch exchange equipped with a function to notify the incoming call while the call is in progress. The job information of the calling extension subscriber of the incoming call during a call is transferred to the display device and displayed, and the calling extension subscriber is notified of the calling extension subscriber without the calling extension subscriber responding to the calling extension subscriber. (identification).

An embodiment of the present invention will be described below with reference to FIG. Second
The figure is a diagram showing an interrupt call notification control system in an embodiment of the present invention. Note that the same reference numerals indicate the same objects throughout the figures. Similarly to FIG. 1, in FIG. 2, an infighting subscriber C who is qualified to interrupt an extension subscriber A who is on a call with an extension subscriber B via a communication path 1-1 in network l. When a call arrives, the central control unit 21i is busy referring to the status monitoring memory of extension subscriber A and the data memory of extension subscriber C in the main storage device 3 as described above, and shortens extension subscriber A. Communication path 1- in time network 1
1 to 1-2 After changing the K connection and allowing the user to listen to the interrupt sound sent from the interrupt sound trunk 6, the entire conversation with the T-line subscriber B is continued again, while the extension subscriber CK is connected to the network 1. The communication path 1-3 is set to listen to the interruption notification sound sent from the trunk 7. At the same time, the central control unit 2 sends the call line subscriber C# from the extension CO data memory in the main storage device 3. ◎The display WJA driving device 19 extracts job-specific information, for example, the first number, and transmits it to the display driving device 9. &Knowable place I
The installed display device 10 is driven to display the extension number of the extension subscriber C.0 The common subscriber A hears the interruption sound and the extension number displayed on the display device 10, and calls the extension subscriber C. When the controller learns that an incoming call has arrived, determines which call should be prioritized, the currently calling extension subscriber B and the newly received extension subscriber C, and gives priority to the call with extension S subscriber B. The side call is cascaded to the valley, and extension subscriber CK is placed on standby while listening to the interruption notification tone.◎As long as extension subscriber C is on standby, the display device fllllO will be the same as that of extension subscriber C. Continue to display the extension number. If priority is given to a call with extension subscriber C, hooking is performed in the same way as in FIG. The central controller 2 responds to the extension subscriber CK, and in the meantime, allows the extension subscriber B to listen to the hold tone sent from the hold tone trunk 8 via the communication path 1-5. When subscriber C is answered - or if extension subscriber C abandons the call due to waiting for extension subscriber A4D response, display &
Sends an erase instruction to the moving device 19 and displays the display device 111.
10 to erase the extension number of extension O subscriber C currently displayed.

As is clear from the above explanation, in this embodiment, extension subscriber A informs extension subscriber B that the caller of the incoming call is extension subscriber C and 021! It is possible to know without interrupting the I-line call, and it is possible to directly judge which common-law subscriber Bt or C should be prioritized for a call.

It should be noted that FIG. 2 is only one embodiment of the present invention, and for example, the display device is not limited to being installed separately from the extension subscriber (telephone) A; Although the display may be performed using four wires, the effect of the present invention does not change even in such a case.In addition, the display drive device fj19 can be used to drive one display device m1 (l). The effect of the present invention does not change even in the case where the display device *io of the internal subscriber AFi is driven in common, but the effect of the present invention does not change. There is no limitation, and for example, numerous modifications may be considered in which KjM notifications are received during a call with a trunk line, but in any case, the effects of the present invention remain the same. The identification information of call extension subscriber C is not limited to the extension number (although the effects of the present invention do not change even in the case of other identification information). It goes without saying that the invention is not limited to what is shown in the figures.

As described above, according to the present invention, in an automatic private branch exchange equipped with all functions for notifying an incoming call, the extension subscriber who receives the incoming call notification does not have to respond to the caller of the incoming call. The calling extension subscriber can be identified in advance, and it can be immediately determined whether to give priority to a call in progress or an incoming call in progress, and both calls can be processed smoothly.
